Add two tests to pmtu.sh, for verifying that PMTU exceptions get
properly created for routes that don't belong to the main table.
A fib-rule based on the packet's DSCP field is used to jump to the
correct table. ECN shouldn't interfere with this process, so each test
has two components: one that only sets DSCP and one that sets both DSCP
and ECN.
One of the test triggers PMTU exceptions using ICMP Echo Requests, the
other using UDP packets (to test different handlers in the kernel).
A few adjustments are necessary in the rest of the script to allow
policy routing scenarios:
* Add global variable rt_table that allows setup_routing_*() to
add routes to a specific routing table. By default rt_table is set
to "main", so existing tests don't need to be modified.
* Another global variable, policy_mark, is used to define which
dsfield value is used for policy routing. This variable has no
effect on tests that don't use policy routing.
* The UDP version of the test uses socat. So cleanup() now also need
to kill socat PIDs.
* route_get_dst_pmtu_from_exception() and route_get_dst_exception()
now take an optional third argument specifying the dsfield. If
not specified, 0 is used, so existing users don't need to be
modified.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
